Is DDT Morally Right or Wrong?

Rachel Carson wrote a book called Silent Spring that details the relationship between man made chemical compounds and the environment. Through this book, much needed reform took place nationally as well as locally. It can even be said that Rachel Carson was a pioneer some 50 years before the modern day Green Movement. With these great changes, a new, unexpected issue arose in Africa. Every year between 350-500 million people die from Malaria with 90% of those being in Africa. Africa's moderate climate harbors a large constigency of the mosquito carriers.The most basic and effective treatment against this deadly disease is chemically treated netting, household and community wide insecticide spraying as well as periodic spraying. Should regulations be laxed in order to provide a more effective anti-malaria treatment?

Mitochondrial Eve

Mitochondrial Eve is a select field of study in human genetics. Its main focus is on the idea of a direct link between all humans to a single ancestor. It has been estimated that Mitochondrial Eve lived around 200,000 years ago. This theory came about through the genetic idea that maternal descent goes through a mother and her mother and eventually her mother to the point of all female linages converging. With this said, people from completely different continents should have some genetic similarities.

As anyone can see, the physical diversity is obvious. A deeper look though, into the genectics of each person will reveal a common link between each group.
